Project: Gutenberg [1] Date: 2019-September-25 Security risk: *Critical* 16∕25 AC:Basic/A:None/CI:Some/II:Some/E:Theoretical/TD:All [2] Vulnerability: Access bypass

Description:  This module provides a new UI experience for node editing - Gutenberg editor.

The routes used by the Gutenberg editor lack proper permissions allowing untrusted users to view and modify some content they should not be able to view or modify.

Solution:  Install the latest version:

* If you use the Gutenberg module 8.x-1.x, upgrade to 8.x-1.8 [3] * For roles other than administrator, the Administer Gutenberg permission must be given to handle media files on the Gutenberg editor.

Also see the Gutenberg [4] project page.
